ABSTRACT:
The present invention discloses a tactile feedback device for giving realistic touch sensation to the user by stimulating the skin of the user. The tactile feedback device of the present invention comprises a housing having one end positioned near the skin of the user in use, an actuator, touch pins and an elastic means. The actuator is mounted inside the housing to convert electromagnetic energy into kinetic energy. The touch pins are mounted inside the housing so as to pop in and out, and the front end thereof is popped out of one end of the housing to contact the skin, and is connected with the actuator so as to be operated by kinetic energy of the actuator. The elastic plates of the elastic means are mounted between one end of the housing and the actuator, and have the touch pins fixedly passing through so as to be interlocked with the touch pins, and when the touch pins pop in and out, they are elastically deformed to have elastic energy. According to the present invention, the touch pins stimulate the skin of the user by dint of an interlocking structure of the actuator that converts electromagnetic energy into kinetic energy and the elastic means, so it is possible to implement realistic touch sensation.
